Floyd Mayweather has revealed he will pocket a staggering $9,000,000 for just nine minutes work.

The undefeated boxing legend came out of retirement for an exhibition fight with Japanese kickboxing knockout artist Tenshin Nasukawa .

Mayweather, 41, travelled to Tokyo to top the bill for the RIZIN 14 super show at the Saitama Arena.

Nasukawa, 20, has not lost in 28 kickboxing fights, boasting an incredible record of 22 wins by way of knockout.

Mayweather stunned the world of boxing when he agreed to take part in a special exhibition fight with Nasukawa – but the bout will not count towards his 50-0 unbeaten record.

In three rounds under boxing rules, multi-millionaire Mayweather revealed on Instagram he will walk away with an eye-watering sum for his efforts.
